Video Analysis of the Precision Process for Motor Magnet Insertion—Jiuju Motor’s Automated Assembly Line

The precision of the motor magnet insertion process is critical to the overall operational stability of the motor. The assembly has an extremely narrow tolerance; even a deviation of just 0.1 millimeter in magnet insertion can directly cause a 5% drop in motor efficiency. Misalignment in the arrangement of the magnets leads to an uneven magnetic field distribution in the air gap, resulting in a series of issues such as increased electromagnetic losses, greater torque fluctuations, and higher operating noise. Long-term use can also increase bearing loads and shorten the service life of the entire unit. To ensure motor energy efficiency and smooth operation, it is essential to strictly control the positioning accuracy of magnet insertion. This requires the use of automated equipment featuring vision-based positioning and closed-loop calibration to eliminate manual assembly errors. Through standardized tooling and real-time inspection, magnetic assembly errors can be strictly confined within acceptable limits, thereby preventing magnetic field imbalance defects at the source, stabilizing motor output efficiency, and reducing subsequent failures and energy consumption.
